Academic (or Research or Clinical) Interests

Dr. Reinisch, MD, graduated at the Medical University of Vienna (MUV), where he finished his training in Internal Medicine and Gastroenterology. After initial scientific studies in oncology at the MUV and the National Cancer Institute, Frederick, MD, he decided to focus his research interest on inflammatory Bowel disease (IBD). Dr. Reinisch is founding member of the European Crohn’s & Colitis Organisation (ECCO) and was assigned as honorary member after having contributed in various positions. He was active in the Scientific and Public Affairs Committee of the United European Gastroenterology (UEG) and headed the Austrian IBD Study Group. Dr. Reinisch is member of the International Organization For the Study of Inflammatory Bowel Disease (IOIBD).

Dr. Reinisch is an expert in designing, conducting and interpreting the results of clinical trials in IBD. He envisions a customized management of IBD utilizing the innovations of translational medicine. He advocates the implementation of a "common language of inflammatory bowel disease" to improve the communication with patients and between physicians for a better care and more robust research outcomes.
